KNITTING raricrrrnn. 7

Application filed February 10, 1920. Serial No. 357,802.

' To all whom it may concern:

Britain, and resident of the city of T oronto,

county of York,-Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Knitting Machines, described in thefollowing specification and illustrated in the accompanyingdrawings. 7

The principal objects of this invention are,'to effectively accomplish the reverse knitting of tubular articles, and to devise a machine which may be operated at high speed with accuracy and without injury.

A further object is to devise a construc tion for reverse knitting machine which may be very quickly and accurately adjusted and which may be retained rigid in its adjusted position.

The principal feature of the invention consists in the novel construction and arrangement of parts, whereby an adjustable tubular guide is rigidly supported axially above the needle cylinder andthe knitted fabric is guided thereby.

In the drawings, Figure 1' is a side elevational view of my improved arrangement.

Figure 2 is a plan view.

In the manufacture of tubular knitted. goods it is found desirable forcertain classes of goods that they be made with a reverse stitch, that is to say, the continuous chain stitches are arranged on the'outside presenting a smooth surface instead of a ribbed surface.

In order to accomplish this result the fabric is knitted upwardly instead of down wardly, that is to say, the knitted tube instead of passing downwardly through a hollow central needle cylinder is knitted in an upward direction from the needles. This results in the rib being formed on the inner side of the knitted tube. In order to achieve this result it is necessary to provide some form of a guide to hold the stitches from slipping off the needles and a tubular guide 1 is arrangedvabove the needle cylinder-2, the lower end being spaced a short distance from the top of the needle cylinder to allow the fabric to pass from the needles into the guide as it is knitted. V

The guide is required to be adjustably supported but when adjusted a desired distance above the needle cylinder it must be held very rigidly, for if it gets out of alignment with the needle cylinder the needles become fouled thereagainst which results in the breakage of the needles or the tangling of the same in the woven goods through their whipping into the interior of the guide.

In order to rigidly hold the guide 1 I have arranged the rods 3 and 4 which are rigidly secured in the rotatable spider 5 secured to the rotatable cam holder 6.

An arm 7 is formed with a split boss 8 encircling the rod 3 and this arm extends over the axial centre of the needle cylinder having an enlarged collar portion 9 adapted to be held in axial alignment with the cylinder;

The arm is slotted longitudinally at one side of the collar and a set screw 10 extends through the slotted portion in order to tighten the collar. A lug 11 projects outwardly from the collar 9 preferably in alignment with the arm 7, and a block 12 is slidably secured to said lug by the screws 13 which extend through a longitudinal 7 slot 14 in said block.

The outer end of the block is formed with a transverse slot 15 and a set screw 16 extends through the said transverse slot into a threaded orifice in the upper end of the rod 4.

The tubular guide 1 is threaded externally and the collar 9 is correspondingly threaded so that the guide may be adjusted vertically by being turned in its threaded support and the upper end thereof is preferably formed with a knurled flange 17.

The lower end of the guide 1 is flared outwardly to come into close relation with the inner sides of the needles and the inner wall is flared outwardly to the lower edge.

A guide structure such as described is extremely simple. It is very rigid and capable of very accurate adjustment and the threaded support of the tubular guide allows of the said guide being moved rapidly out of the way of the needle cylinder with out disturbing its alignment to enable the ready access to the needle mechanism.

What I claim as my invention is 1. In a knitting machine, the combination with the stationary needle cylinder and the rotatable cam block, of a rigid frame secured to the cam block and extending over the cylinder and havinga threaded collar arranged in axial alignment with the cylinder, and a tubular guide threaded in said collar and adapted to extend downwardly into close proximity to the top of the cylinder. r

2. In a knitting machine, the combination with the stationary needle cylinder and the rotatable cam block, of a pair of rods rigidly secured in the cam block and arranged diametrically opposite, an arm slidably and pivot-ally mounted on one of said rods and extending over, the cylinder and adjustably connected to the other of said rods, and a tubular guide held in said arm above the cylinder'and adapted to be cally. or

'3. In a knitting machine, the combination with the stationary needle cylinder and the adjusted vertirota-table cam block, of a pair of rods rigidly secured in the cam block and arranged diametrically opposite, an arm slidably and extending over the cylinder, 3; block adjustablyvsecured upon the freeend of said arm and having a transverse slot adapted to register With the top of the other of 20 pivotally mounted'on one of'said rods and through said transverse slot into the rod beneath said block to loclr'said block and saiclarm rigidly between said rods, and a tubular guide supported in said arm in axial alignment With the cylinder and adapted to be vertically adjusted therein.
